It may be that we make a thermostat and it is not worth spending an ATMega328p and use the ATTiny85.
Still, it is clearly at a disadvantage, but as I said at the beginning: everything has its place. It is true that in power they could be compared, since certain models of the ATTin圓28 can reach 20Mhz with an external oscillator. Furthermore, the consumption of ATTiny85 is half that of ATMega328.Īs disadvantages we can find that it has much less IO ports, less memory of all types (SRAM, EEPROM and program). If we compare it with the ATMega328p we find a microcontroller that takes up much less (speaking of the standard package of DIP8 vs DIP28). In the case of the ATTiny85 it can be for cases where we need a microcontroller that uses less and consumes equally little. Like everything in this world, everything has its use.
